You forget HD texture mods. For example for Skyrim. Together with 4xSSAA 2GB memory are easily exceeded, even on 1920x1080.

I own a 7970 and for me, SSAA is a must. I don't understand why SSAA isn't benchmarked. It's the best use for your monster graphics card if your FPS exceed 60FPS without it. It just looks so much better than just MSAA (at least if you are not jaggie blind)

It would be nice to run the same tests with (at least) 2-way sli.
And then, run the whole thing again with 2560x1440@120Hz, surround/infinity of 2560x1440 @60Hz and then @100Hz (since nVidia drivers are bogus in sli).
Finding such a monitor is not easy, though, so I guess sticking to 60Hz at first would be ok.

"This is the most resource-consuming application on our list. It needs 1.3 gigabytes even at 2560x1440 without antialiasing and 2 gigabytes with 4x MSAA."

Nope, this bench doesn´t use Multisampling antialiasing, it uses SUPERsampling (in the file "settings.ini" you can config the test, you can use supersampling, 2.25x or 4x, and not to use it).

The tremendous waste of memory with antialiasing in this test is related with the supersampling technique. With 2560x1440 and 4x, you are using "internally" 5120x2880 (56 MB in one framebuffer with 32 bits of color) and downsampling it.

Please add CUDA code testing. These test for games are not interesting. I suggest you to write a CUDA code that will use 4 GB of memory or more and will run for several hours. These results would be interesting. Also CUDA on dual gpu or triple. Thanks in advance.
